BALL-BEARING.

SPECIFICATION forming art of Letters Patent No. 606,491, dated June 28, 1898.

i Application filed January 19, 1898. Serial No. 667,146. (No model.)

To all whom/it may concern:

Be it known that I, J QHN RANDOLPH SAU- CIER, of New Iberia, in the parish of Iberia and State of Louisiana, have invented a new and Improved Ball-Bearing, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved ball-bearing more (espe cially designed for use in the step for the vertical shaft of a heavy machine rotating at a high rate of speed, the arrangement being such as to dispense with the use of high-grade lubricants and at the same time permit of running the machine at a high rate of speed without overheating the hearing;

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures. Figure 1 is a sectional side elevation of the improvement, and Fig. 2 is a sectional plan view of the same on the line 2 2 of Fig. 1.

The improved ball-bearin g is provided with a cup-shaped casing A, secured at its upper end by bolts B to a flange C, attached by bolts D to a supporting-timber E or other foundation. Within the casing A are formed projections A, adapted tovbe engaged bylugs or flanges F, formed on a box F, suspended within the casing A by the lugs resting on the projections A.

The box F is made cup shape and is provided with a lining G, of brass, the lower end of which extends in an annular groove below the bottom of the box, as is plainly indicated in Fig. 1, the upper end receiving the lower end of a shaft II, carrying the parts of the machine to be rotated at a high rate of speed. The bottom of the shaft H rests on the top surface of a button I, fitted within the lining G and located above a second button J, resting on the bottom of the box F, as is plainly indicated in Figs 1, the said buttons I and J being formed on their opposite faces with annular grooves or ball-races I J, respectively filled with balls K of a size sufficiently large to hold the two buttons slightly apart, as

, plainly indicated in Fig. 1.

The lining G and the box F are formed with apertures L L, arranged at different heights and connecting the inside of the casing with the inside of the lining to permit the lubricantcontained in the casin g Ato pass through the said apertures to the inner surface of the lining and to the parts contained therein that is, the lower end of the shaft II and the ball-bearing consisting of the buttons I and J and the balls K. It is thus that the oil-box communicates with the interior of the casing. The upper end of the lining G is preferably flared outwardly, as at G, to permit of conveniently inserting the lower end of the shaft H into the lining when the machine is mounted.

Now it will be seen that by having the lower end of the shaft II resting loosely on the button I the weight of the machine will cause the button to rotate with the shaft II, and the button will rotate upon the balls K, traveling at a lower rate of speed in the annular grooves or races 1 J of the buttons I and J. v

Now'by the arrangement described the ma chine, with its shaft II, can be rotated at a veryhigh rate of speed without requiring a lubricant'of first quality and without danger of overheating the bearing, as the friction between the revolving parts is reduced to a minimum owing to the interposition of the balls between the buttons I and J.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. A ball-bearing comprising a cup-shaped casing formed at its inside with a support, an oil-box hung on the said support within the casing, a button set in the bottom of the box, and formed on its top with a circular groove, a second button above the first-named button, and on which rests the lower end of a shaft, the second button being provided in formed with apertures for admitting oil from the casing to the inner surface of the lining and the parts contained therein, abutton set in the bottom of the boX, and formed on its top with a circular groove, a second button above the first-named button, and on which rests the lower end of the shaft, the second button being provided in its under side with a circular groove registering with the groove in the other button, and balls filling the said grooves for holding the buttons separated, substantially as shown and described.
